Hey man. I don't frequent these parts much anymore, but I know Salty and I assure you, he's not trying to be a ****. Your map at its current form will not make it to matchmaking, nor will it be a big hit in the community, which are the only two things you can really strive for in Forge. The issues range from pathways, line of sight, to visuals and other issues. I think at this point your best option is to shelve this map for now. Build a few smaller maps, hone your abilities and attempt to create a true competitive arena. This is the equivalent of learning to walk before you run. Hell, you can even revisit this map idea once you learn the basics of how Halo combat takes place within your geometry. This isn't a slight against you. If I knew about ForgeHub when Reach came out I'm sure the older heads on here would be giving me the same advice. Consider what Salty and I have said to you as some "tough love". All the best dude.
